Never used these before. But they look better made than the set i now use. And the set i have now are worn out, so i thought i would try these. They look like they will hold up, and align a little better then my current set.

i had purchased these about two months ago an i am really glad i did i was trying to mount hinges on doors and cabinets with my eye and a drill bit which was getting me no wear so i bought these what a life saver job done in half the time i would recommend

No sir, The 7/64 self centering bit is made for drilling pilot holes to install Interior door hinges Not for Furniture Hinges or Cabinet Hinges you need 5/64 self centering bit for softwoods such as poplar or pine but if you are using Hardwoods such as Maple,Oak,Hickory,,etc you will need 3/32 self centering bits

BEST ANSWER:If I remember right, the centering barrel unscrews from the drive end of the centering bit assembly. The barrel is under spring tension so watch for the spring action when it is fully disengaged from the drive end. You should then be able to remove the drill bit and spring from inside.

BEST ANSWER:I believe there is a small allen set screw that must be removed if you want to remove the drill bit from the mechanism. Also the forward spring mech can also be unthreaded and removed which helps getting the old bit out.

BEST ANSWER:Yes, the set comes with a #4 bit plus a #6 and #8. Personally, I'd get the whole set for $30 since they cost $13 for a single one. If your heart is set on just the #4 bit then look for Item #: 68984.

Reviews

I've had these for a few years and have used them a few times off and on. Mine have proven to stick open requiring constant attention to retract the spring loaded cover before drilling the next hole. Yesterday the #8 retractible cover just pulled through the sleeve completely, thus rendering the unit unusable. Other customers have given this set high marks so maybe I'll try to get customer service to replace mine as duds.

The small bit #4 broke on the first set of hinges I used it on. The collar on the replacement stuck but WD40 seemed to help. They were quick in replacing it but it broke again. A couple weeks later the #6 broke while I was using it. The best thing about the set is the case for keeping the bits together.

First the #8 bit broke, then the #6 bit broke, after just a couple of successful uses. Now I have to explain to the client why I can't use all three screws in their new door hinge - because the bit broke off where the screw is supposed to go.

This set replaces some old ones I have that were made in Taiwan and they make them look like junk. Glad to see these were made in the USA. I did not think there could be that much difference in them. These are much smoother than my old ones. Very easy to clean out also.

Great idea. The first couple of times I used it it worked a treat, then the trouble started. Not sure if I received a dud set but the metal on the nose is shattered on the small bit and then a while later one of the drills broke off in a hole. What a mess!

I have had many troubles in the past trying to get the screw hole drilled in the center of my hinges. Not anymore. These things work great. I saw other reviews about broken bit trouble but I have yet to have a problem with mine. Sure the collar may stick a little when wood gets wedged inside it but that is understandable. I will definitely be using these on all of my hardware projects where a centered hole is needed.

If you have ever misaligned centering screws in a hinge to the point where you pull the hinge out of square. you'll like the these. First use the bit in one screw hole then tighten the screw. This holds the hinge tight for drilling subsequent holes.

I have also found the bits useful in limiting the depth of a drilled hole.

I've been using this type of bit for quite awhile. It's nice to have a set to use in the Bosch PS20. I've only used the #4 so far and can say it worked as expected. I recommend them to anyone who mounts hinges and has any of the popular, small, cordless drivers.

Wow! What a wonderful find at a price that's right. This has helped tremendously with installing cabinet door hinges. All of the guess work in finding and drilling was eliminated and the ease of use...well, all I can say is I'm glad I found this set.

I purchased a set of self-centering Vix bits from Rockler several years ago. The Insty-Drive feature makes these even better. I use them any time I need to center a hole in hinges, drawer slides, shelf brackets, etc. And, there's a set screw to lock in the drill bit so you can adjust the depth of the hole.

The newer design works just as well as the old design but the newer ones take readily available jobber drill bits. So now, when you break a bit you can pick up a replacement easily as opposed to the older design that used a proprietary length drill bit (which cost about 10x more).

I've found the entire Rocker Insty-Drive system to be very useful. The quick change feature is very handy. The centering bits work well, but I find they clog up and jam the barrel faster than a Vix bit. It appears they have a closer tolerance around the drill than the Vix. Overall they are very good.

Used with a Jig-It, the self-centering bits were a real labor saver. They are a bit fragile, though. The nosepiece on the #8 bit was sticky and did not return to cover the drill tip well. After driving about 30 pilot holes, it snapped off. Treat them delicately.

They are very good to use for installation of hinges ,You never drill the holes too deep or too shallow ,it is always same depth, & the pilot hole is always in the center for hinge screws& that helps keep the door aligned.

I have only used them for one project so far, but they worked great. Smooth action and accurate. Far superior to a cheaper set I bought from a national chain that specializes in selling inexpensive imported tools.

It seems easy enough to put a pilot hole in the center of a hinge,etc. But if they're a little off it can mess things up. These do exactly what they are supposed to do. I don't do a lot of cabinets, or other things that involve hinges, but when I do I certainly use these.
